Integral air brick for ferrosilicon ladle and preparation method of integral air brick
The invention discloses an integral air brick for a ferrosilicon ladle and a preparation method of the integral air brick, and relates to the technical field of integral air bricks, the integral air brick for the ferrosilicon ladle comprises a brick core, the brick core comprises a circular truncated cone-shaped brick core, a plurality of air supply channels are distributed in the brick core along the axial direction, the side surface of the brick core is coated with a stainless steel shell, and the stainless steel shell is arranged in the brick core; a sealing steel plate welded to the stainless steel shell is arranged on the large end face of the brick core, a through hole is formed in the center of the sealing steel plate, and a gas supply steel pipe used for conveying gas to the gas supply channel is arranged at the through hole. The brick cup wraps the outer side of the brick core, and the small end face of the brick core and the air supply steel pipe both penetrate to the outer side of the brick cup. According to the integral air brick for the ferrosilicon ladle and the preparation method of the integral air brick, the integral air brick does not react with ferrosilicon melt and smelting slag and is high in strength and resistant to scouring; the brick core can be protected, and the service life is prolonged.
本发明公开了一种硅铁包用整体透气砖及其制备方法，涉及整体透气砖技术领域，硅铁包用整体透气砖包括：砖芯，所述砖芯包括圆台形砖芯，砖芯的内部沿其轴向布设有若干供气通道，砖芯的侧面包覆有不锈钢壳体，砖芯的大端面设有与不锈钢壳体焊接的密封钢板，密封钢板的中心处开设有通孔，所述通孔处设有用于将气体传送至供气通道的供气钢管；座砖，所述座砖包裹在砖芯的外侧，所述砖芯的小端面和供气钢管均贯穿至座砖外侧。该硅铁包用整体透气砖及其制备方法，不与硅铁熔体及冶炼渣反应，强度高，耐冲刷；可对砖芯进行保护，提高使用寿命。
